When compression exceeds the optimal limit for boost, heat isn't the issue, but rather peak cylinder pressure. Sure, there are 10:1 turbo modular Mustangs out there. In fact, there's one here in Knoxville. But guess what, he has to run 15* @ 9psi. This is what we call a knock-limited motor. It cannot be tuned to mean best torque timing.180sx wrote: ok have you ever been in turbo rsx? High Compression and a snail , so they do mix quiet well just size ur snail right and tune it properly. Or feed her alky that will take care of heat.
If you go v8 ur car will be so off balance.s13 is 50/50 front to back,urs will be 80/20. V8 has alot more moving parts as well vs a4banger.So if you ever fix/rebuild you will pay for 8 rods and 8 pistons etc.Those were my primary dislikes about throwing in v8's. Not to get into mounting issues etc.
My preference would be a six like 1 jz.But $ per horse you right just go and rob a stang at a local yard.
As for the balance, well, that's just silly. As already pointed out a couple times, the 302+alluminum heads weighs less than a built KA-T. If I go with a pair of small turbos, the balance might shift to 60/40 at worst, considering FMIC and extra plumbing.
Additionally, the 302 will sit lower in the engine bay, making the center of gravity lower, aiding in overall performance.
In the end, it's just a better setup. My decision has been made. 302 is what I'll be using, with alluminum heads and either a TT or single T setup, either of which will be focused on daily driving, street/strip fun.
MS-II is being ordered this weekend, so the KA will be running on it for a short time, until the V8 parts are ready to go in. Once the swap is done, it'll be run with MS-II as well.
